The fifth-generation iPod Touch offers the same 4-inch display found on the new iPhone 5 and includes a more powerful A5 processor and a 5-megapixel camera. The new Touch comes in both 32GB and 64GB versions and offers a choice of five different colors. Some models list an estimated ship date of two to five weeks; others three to five weeks. The 64GB pink version shows a wait time of one to two months.

The 32GB version sells for $299, while the 64GB model goes for $399.

The seventh-generation iPod Nano has grown in size, offering a 2.5-inch display. The new Nano comes with 16GB of storage and sells for $149. Buyers can choose among seven different colors -- silver, slate, purple, green, blue, yellow, and pink. Some models point to a ship time of two to five weeks and others three to five weeks. But as with the new Touch, pink seems to be playing hardest to get, with an estimated wait time of one to two months.

The fifth-generation iPod Shuffle offers 2GB of storage and a choice of the same seven colors as those for the Nano. Depending on the color, shipping dates from Amazon range from two to five weeks all the way to one to two months.
